General "Woof" Tip: One of the things I would like to pay your attention at:There are many resellers around the Internet which are not direct makers and sometimes don’t even know how and what for products they sell are made.Ask right questions to find out if you deal with main source or if you are going to pay extra money just because product you are about to purchase went through 2-4 extra hands before it reaches you.I like to save extra buck and it won’t harm you either, so check if you are purchasing product from main source.Most of the times if you ask fro a small change in size adjustment, only maker will be able to do it for you.
